Juan, Your proposal for attributes to record the generator, and 'profile' seems like a good one to me. I think many people would find it useful. I have added it to the list of things to consider for MathML 3. Specifying the values for the 'profile' will take some thought. From your examples, I can see your general idea, but I can imagine that attribute recording a number of different things. In particular, your "TeX-annotation" example seems like it would be redundant with the the annotation itself, since that <annotation> element would have a encoding attribute. Would you like to say more about your ideas on that? Thanks for the constructive suggestion. --Robert Robert Miner Director, New Product Development W3C Math Working Group co-chair Design Science, Inc. 140 Pine Avenue, 4th Floor Long Beach, California 90802 USA Tel: (651) 223-2883 Fax: (651) 292-0014 robertm@dessci.com www.dessci.com ~ Makers of MathType, MathFlow, MathPlayer, WebEQ, Equation Editor, TexAide ~ > -----Original Message----- > From: www-math-request@w3.org > [mailto:www-math-request@w3.org] On Behalf Of > juanrgonzaleza@canonicalscience.com > Sent: Thursday, July 27, 2006 6:00 AM > To: www-math@w3.org > Subject: Suggestion about generators of MathML code > > > MathML was developed to facilitate the transfer and re-use of > mathematical > content between applications. > > However, since each tool generates|understands completely > different code > we cannot develop a generic parser receiving content MathML code from > several authors using different software. > > The problem increase with feedback.
